Trail Maintenance

Portola Redwoods State Park
Summer 2000


Many trails in Portola Redwoods State Park have suffered from feral pig damage, winter storm erosion and deferred maintenance. Some of the trails are quite steep, compounding the erosion problems.

     On successive California Trail Days in 1992-1993 and again in 1995, Trail Center volunteers helped build Upper Coyote Ridge Trail, which connects the Tarwater Gap parking in Pescadero County Park to Coyote Ridge Trail (CCC crews completed the southern half).

Project Description:

Coyote Ridge Trail and Upper Coyote Ridge Trail (July 15, 2000): We repaired several segments on Coyote Ridge Trail(western leg) between the Visitor's Center and the Upper Coyote Ridge junction (approximately 200 feet total), primarily by clearing out debris on the inside of the trail tread and clearing brush. Severe outslope in several locations had made walking the trail difficult and were brought back to a gentle outslope. We also cleared approximately 150 feet of brush on Upper Coyote Ridge Trail and increased the trail to full width near the point where the trail crosses over the ridgetop, 1/2 mile from the Tarwater Gap parking. north end

Slate Creek Trail and Summit Trail (August 19, 2000): We cleared the trail in numerous places along Summit Trail and Slate Creek Trail between the Summit Trail junction and Slate Creek Trail Camp. We cleared out debris accumulated on the inside of the trail, repaired retaining walls and eroded areas.

Slate Creek Trail (November 18, 2000): We will construct a 30 foot puncheon across a boggy section of Slate Creek Trail between the Summit Trail junction and Slate Creek Trail Camp. We will clear out debris accumulated on the inside of the trail and repair eroded areas.
